CHemistry
Rubric
Inside of the Grade nine subject course chemistry will have the steps on how to create a scientific theory by following the steps of the scientific method you will learn the types of mixtures and the history of the atom that shows how the models of the atom developed over time including different types of molecules and mixtures thigs such as pure substances and pure mixtures.
Periodic table
The periodic table of element is the table with almost all of the element ever to exist and create there are different types of elements such as metals and non metals non metals include reactive non metals and Noble gasses that have a balanced valence shell. On the other side we have metals there are alkali metals the have a higher chance to lose an electron becoming and positive ion. Continuing the Alkaline earth metals are highly reactive and squishy most likely to lose 2 electron becoming +2 ion and more.
Materials
Working with the real representations of element you may need to have the right tools too make sure you complete those tasks safely and correctly. When working on a lab you will need safety equipment like: safety goggles, and glasses, lab coats, hair ties, and gloves to be safe and have fun when we do our labs. As well labs need special tools and materials to go on with the experiment like a flask beaker graduated cylinders and test tubes.
Conclusion
This is the part where is should summarize everything said before and will add a bit more to that too. Okay the Chemistry grade 9 class is mandatory it explains the fundamentals of atoms and molecules exploring the idea of creating compounds mixture and pure substances. Through the events that may take place before those you will be given a mandatory safety test no matter what grade you are or age. the study of atoms is called the Atomic Molecular Theory.
